A multidisciplinary study on the effects of phloem-limited viruses on the agronomical performance and berry quality of Vitis vinifera cv. Nebbiolo

► Proteomic and grape quality analyses of healthy and GLRaV-1/GVA/RSPaV virus infected grape berries revealed minor differences. ► Significant differences were seen for 12 pulp spots and 7 skin spots out of about 400 spots per tissue. ► Virus infection mainly affected proteins involved in the response to oxidative stress in the berry skin. ► Proteins related to cell structure metabolism were the main target of virus infection in the pulp.
